Answer:
B. It has a stable octet and is unreactive.
Explanation:
s orbital contains 2 electrons and p contains 6. When the outermost energy level of an element has a total of 8 electrons we call it stable octet and it is unreactive. Therefore the answer is B
In nuclear physics and nuclear chemistry, nuclearfission<span> is either a nuclear </span>reaction<span> or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei).</span>
The correct answer is option B. A molecule is two or more atoms (same or different) bound together. It is the smallest particle in a chemical element or compound. Molecules are held together by chemical bonds. These bonds are formed by the sharing or transfer of electrons between atoms.
Answer:
The meaning and usefulness of the mole Page 2 2 • One mole of NaCl contains 6.022 x 1023 NaCl formula units. Use the mole quantity to count formulas by weighing them. The mass of an atom in amu is numerically the same as the mass of one mole of atoms of the element in grams.
Explanation:
ºF = ºC x 1.8 + 32
ºF = 17 x 1.8 + 32
ºF = 30.6 + 32
= 62.6ºF
hope this helps!
